[ H±5.5 ] Withdrawal after drilling
Distance or coordinate the longitudinal axis returns to, in rapid (G00), after each drilling step.
"J" other than 0 means the distance and "J=0" indicates the relief coordinate or absolute coordinate
it withdraws to.
If not programmed, the longitudinal axis returns to the reference plane.
[ J4 ] Drilling passes to withdraw to the starting plane
Defines after how many drilling pecks the tool returns to the reference plane in G00. A value between
0 and 9999 may be programmed.
When not programmed or programmed with a "0" value, it returns to the position indicated by H (relief
position) after each drilling peck.
• With "J" greater than 1, after each peck, the tool returns the distance indicated by "H" and every
"J" pecks to the reference plane (RP).
• With J1, it will return to the reference plane (RP) after each peck .
• With J0, it will return to the relief position indicated by H.
[ K5 ] Dwell
Defines the dwell, in hundredths of a second, after each drilling peck until the withdrawal begins.
If not programmed, the CNC will take the value of "K0".
[ L5.5 ] Minimum drilling peck (step)
It defines the minimum value for the drilling peck. This paramater is used with "R" values other than
1. If not programmed or programmed with a 0 value, it assumes 1 mm.
[ R5.5 ] Reduction factor for the drilling pecks.
Factor that reduces the drilling peck (step) "B". If it is not programmed or is programmed with a value
of "0", it assumes a value of "1".
If R =1, all the drilling pecks will be the same (the programmed "B" value).
If R is other than 1, the first drilling peck will be "B", the second one "R B", The third one "R (RB)"
and so on. In other words, from the second peck on, the new peck will be the product of the R factor
times the previous peck.
If R is selected with a value other than 1, the CNC will not allow smaller steps than that programmed
in L.
